The Wall Street Journal:

There is no more chilling wartime phrase than “I was just following orders.” Surely, most of us think, someone who obeys a command to commit a crime is still acting purposely, and following orders isn’t a sufficient excuse.

Patrick Haggard, a neuroscientist at University College London, has been engaged for years in studying our feelings of agency and intention. But how can you measure them objectively?
